Interesting project! Mini Factorio in 7 days, that is something :) Web build takes time to load, but all works. Very solid map generation. I like every icon and the music!
the map data never gets deleated/saved to disk like in most games it all just sits in ram not a big deal whith a pc build butt web by default has a very small amount of memory sou I had to tell the compiler to reserver more mem which takes a long time
